IMPROVEMENT IN JOURNAL-BOX LININGS.

ATENT Specification forming part of Letters Patent No. 138,641, datedMay 6, 1873; applica on filed January 29, 1873. 1

' To all whom it may concern:

Be it known that I, STUART GWYNN, of the city, county, and State of NewYork, have invented a new manufacture, the same being an Improved Liningfor JournaLBoxes and other rubbing surfaces, of which the following is aspecifica-tion, reference being had to the accompanying drawing formingpart of the Sa-Ille.

On the 12th day of April, 1870, certain Letters Patent of the UnitedStates were issued to me, numbered from 101,862 to 101,869, inclusive,for certain compositions of matter denominated metaline,7 and for theprocess or method of making the same, as also the of nce it performs, towhich reference is made.

The invention herein intended to be described and claimed relates to aspecial mode of applying the said several kinds of metaline or theirequivalent, or any of them,t0 practical use; and consists in acombination of metaline with the material, in the manner and for thepurposes hereinafter particularly described.

Figure 1 is an edge view of a plate of copper, brass, or other suitablemetal, showing the first stage of' one of the modifications of myinvention. t Fig. 2 is a surface view of the same in perspective. Fig. 3is an edge view of the same after it has been subjected to pressure, andthus completed for use. Fig. 4 is a surface View of the same inperspective. Figs. 5, 6, 7, and 8 are similar views, respectively, ofanother modification of my invention.

In carrying out my invention as shown in Figs. l, 2, 8, and 4, a sheetof metal has a number of right-angled channels or grooves cut into itssurface, as shown, to a depth of, say, :half the thicknessV of thesheet. These' f grooves are then filled with finely-powdered metaline,for a description of which, and the method of prepa-rin g which,reference is made to the Letters Patent of April l2, 1870, here-`inbefore alluded to. The sheet with the metaline filling the grooves isthen subjected to severe pressure, preferably by running the samebetween rollers, so as to reduce it considerably in thickness, whereby ie metaline is at once compacted into a sol; mass, and

the metal between the grooves spread laterally at the surface out upon emet-aline,

thereby making the grooves bi1 ader at the base than at the top, forminga d etail space,

as seen in Figs. 3 and 4, and us securely holding the metaline in thegroo s..

' A modification of this invent n is to cast or otherwise fabricateplates wit short studs or pins standing up at short di tances from' eachother over the surface, a i lling the spaces between the pins with pdered met-V aline, as seen in Figs. 5 and 6, d then subjecting theplates thus prepare to pressure,

preferably between rollers, whe by the pins will be flattened or spreadout at; he top, and

the metaline at the saine tim compressed and consolidated, as seen inFig 7 and 8.

It is evident that the form d construction of the plate may be vario lymodified` without departing from the spi tof my invention. For example,grooves; or channels may be out crossing each other t right anf gies, orany angle, so as to fori projections' square, diamond-shaped, or anlother shape desired.`

Pins or wires may be inser d either as studs or staples or loops, the.by forming spaces into which the metaline m t be pressed and held, orrecesses may be ma e in the surfaces by drilling or punching pr tlythrough themetal; the object aimed at b1 ing to make inthe surface of acontinuous s et of metal depressions or channels, into w ch metaline maybe deposited, compacted g y pressure, and securely held, so as not to; edisplaced by use.

In order that the thing desc bedmay be distinctly seen, I have made th`drawing on a somewhat enlarged scale, it i t being advisable, usually,to use metal p tes as thick as represented in the drawing.

For journal-boxes it is desira l e that these plates, when" completed,should e sufficiently thin to be conveniently bent i to a form toconform to the journal for which, hey may 'be intended. l

Such purpose, as has been indicated, is to line journal-boxes andprovide other surfaces subjected to friction in use, With a materialwhich will obviate the necessity of employ ing oil or other extraneouslubricator, an office performed by metaline, as fully explained in mypatents of the 12th of April, 1870, above referred to.

What I claim as a new manufacture is- A sheet of metal, With which isincorporatr ed metaline, substantially'as and for the purposesspecified.

' STUART GWYNN.
